“Sleep Tight,” which world preemed at the Austin Fantastic Fest, is the latest pic from Balaguero, a Sitges Time Machine awardee this year, whose “The Nameless” — produced like “Tight” by Filmax — raised the curtain on Barcelona’s upscale genre pic production.

Written by Barcelona-based producer Alberto Marini, “Tight” stars Luis Tosar (“Miami Vice”) as a sadistic, voyeuristic doorman hell-bent on scaring a tenant (Marta Etura) out of her wits.

A perverse thriller, with echoes of Roman Polanski’s “The Tenant,” “Tight” is a far cry from the shuddering camerawork of Balaguero zombie-fest “REC.” It was hailed by some of Spain’s most influential newspapers as Balaguero’s best pic to date.

Both pics mesh mainstream tropes with some of the psychological complexity of arthouse fare.
